Description
- The present invention refers to a clamping apparatus comprising a chuck member and a pallet member adapted to be releasably fixed to the chuck member. The chuck member comprises clamping means for clamping the pallet to the chuck member and first centering means, while the pallet member has second centering means adapted to cooperate with the first centering means to define the relative position between the chuck member and the pallet.
- Clamping apparatuses of the kind mentioned above are mainly used to fix work pieces in a positionally well defined manner in the machining area of a machine tool. Thereby, the work piece first is fixed to a pallet and then, the pallet is releasably attached to the chuck member. Alternatively, the work piece itself can constitute the pallet. In most cases, the chuck member itself is fixedly attached to the machine tool. Commonly, such clamping apparatuses are used with milling, grinding, polishing and erosion machines.
- A problem in machining the work piece may exist insofar as the machining tool and/or machining fluid jets can excite the clamping apparatus to vibrations, thereby impairing the quality of machining of the work piece.
- The document EP-A-1 044 763 discloses a holder for exactly positioning a work piece in the machining area of a machine tool, the holder being provided with a vibration damper. By providing such a damper, the problems mentioned herein before should be avoided. On the one hand, the holder comprises connecting elements for attaching it to a fixed supporting structure and, on the other hand, fixing means for holding the work piece. The holder is in the form of a so-called leveling or pendulum head to which a work piece is fixed and which can be finely adjusted in three directions. Thereby, the work piece can be very exactly positioned with regard to the machine tool. The above mentioned vibration damper is intended to absorb the vibration energy induced into the holder through the work piece by the rinsing fluid during an electro erosive machining process. As materials for the damper, particularly rubber or rubber-like materials are suggested.
- The document DE-A-199 17 104 discloses another holder provided with a vibration damper. Besides the vibration damper, a region of the holder is provided in which the holder and the supporting structure and/or the work piece are in direct contact. Thereby, a connection shall be realized that is partially hard and partially damped. Such a holder is said to be particularly useful in connection with work pieces subjected to a cutting or lapping operation.
- It is an object of the present invention to provide a clamping apparatus of the kind referred to herein above incorporating a damping element that is stable, has a high rigidity and, simultaneously, provides excellent damping characteristics.
- To meet this and other objects, the present invention provides a clamping apparatus comprising a chuck member and a pallet member releasably fixed to the chuck member. The chuck member comprises clamping means for clamping the pallet to the chuck member. The chuck member has first centering means and the pallet member has second centering means cooperating with the first centering means to define the relative position between the chuck member and the pallet. The chuck member and/or the pallet member are/is provided with at least one damping element consisting at least partially of a compressed composite of metal chips.
- A damping element consisting of a compressed composite of metal chips is relatively stiff and provides very good damping properties in view of the load to be expected during machining a work piece fixed to the chuck and the pallet, respectively.
- In the following, an embodiment of the apparatus according to the invention will be further described, with reference to the accompanying drawings, in which:
-
FIG. 1 shows a perspective view of a chuck and a pallet; and -
FIG. 2 shows a longitudinal sectional view of the chuck and the pallet ofFIG. 1 . - With reference to
FIG. 1 , there is shown a perspective view of thechuck 1 and thepallet 2 including some additional elements to be explained in more detail herein below. The chuck essentially comprises alower portion 3 and an upper portion 4. Thelower portion 3 of thechuck 1 includes acircular base plate 5, acircular support plate 6 and adamping element 7 inserted between the above mentioned circular base andsupport plates chuck 1 comprises acylindrical clamping housing 8, the interior thereof being provided with clamping elements in the form a clamping balls (not shown inFIG. 1 ), and the top thereof being provided with centering elements in the form of protruding centeringpins 9. Thebase plate 5 is attached to a machining apparatus (not shown) by means offixing elements 11. Thesupport plate 6 is attached to thebase plate 5 by means ofscrews 12 adapted to be screwed intoanchor nuts 13. For receiving theseanchor nuts 13, the bottom of thesupport plate 6 is provided with blind holes (not shown inFIG. 1 ). The anchor nuts are manufactured of a ductile, but nevertheless elastic material and provided with a central thread made of steel. The end portion of theanchor nuts 13 facing thebase plate 5 are provided with ashoulder 13 a, the purpose thereof being explained in more detail herein below. - The clamping
housing 8 is fixed to thesupport plate 6 by means ofscrews 14 as well. For receiving thedamping element 7, both thebase plate 5 and the support plate are provided with circular recesses corresponding in size to the diameter of thecircular damping element 7, whereby only therecess 15 provided in thebase plate 5 is visible inFIG. 1 . - The
pallet 2 comprises acircular base plate 17 and acircular support plate 18. The bottom of thebase plate 17 is provided with aclamping pin 19 by means of which thepallet 2 can be clamped to thechuck 1. Moreover, fixed to the bottom of thebase plate 17, a elastically resilient disk (not shown inFIG. 1 ) is provided that comprises a plurality of groove-like recesses, which correspond to the centeringpins 9 of thechuck 1 as far as shape and position is concerned and which serve for determining the position of thepallet 2 with regard to thechuck 1 in X- and Y-direction. Also in this case, adamping element 20 is inserted between thebase plate 17 and thesupport plate 18. Similarly, bothplates circular damping element 20, whereby only therecess 21 provided in thebase plate 17 is visible inFIG. 1 . - In the present example, the
support plate 18 is designed as an integral part of thepallet 2. For fixing the work piece to be machined, the top of thesupport plate 18 is provided with fixing elements, e.g. in the form of bores, which are, however, not visible inFIG. 1 . - Both the
damping element 7 of thechuck 1 and thedamping element 20 of thepallet 2 comprise a plurality of steel chips or swarfs that are compressed under pressure to a squeezed composite of steel chips. The pressure by which the chips are compressed to a composite can amount to between some ten kN up to several hundreds kN. Depending on the particular application, the compressed composite of steel chips can be embedded in a pottant. Preferably, thedamping elements -
FIG. 2 shows a longitudinal sectional view of thechuck 1 and thepallet 2. In this view, it can be clearly seen that thesupport plate 6 and thebase plate 5 are attached to each other by means ofscrews 12. Thescrews 12 are received in theanchor nuts 13, the latter ones expanding radially upon screwing in thescrews 12. Thus, theanchor nuts 13 are rigidly fixed in theblind holes 24 of thesupport plate 6. Due to the fact that thescrews 12 are fixed to thesupport plate 6 by means of ductile, butelastic anchor nuts 13, an elastic connection results between thesupport plate 6 and thebase plate 12 via thescrews 12. Moreover, besides the connection by means of thescrews 12, the twoplates damping element 7. - The thickness of the
damping element 7 is chosen such that a gap S remains between thesupport plate 6 and thebase plate 5 once thescrews 12 have been tightened. Thereby, the thickness of theshoulder 13 a of theanchor nuts 13 is adjusted to the excess thickness of thedamping element 7, with the result that it is avoided that the twoplates screws 12. Preferably, the gap S is filled with a pottant or at least sealed along its edge to prevent any dust, fluids, chips or similar from penetrating into the gap S. - Furthermore,
FIG. 2 shows the elasticallyresilient disk 10 fixed to the bottom of thepallet 2 and provided with a plurality of groove-like recesses, which correspond to the centeringpins 9 of thechuck 1 as far as shape and position is concerned and which serve for determining the position of thepallet 2 with regard to thechuck 1 in X- and Y-directions. For positioning thepallet 2 in Z-direction, distance pins are provided (not shown inFIG. 2 ), preferably attached to thepallet 2. As is known in the art, thepallet 2 is clamped to thechuck 1 by means of clampingballs 23 engaging a shoulder of the clampingpin 19 of thepallet 2. - The damping
element 20 located between thebase plate 17 and thesupport plate 18 is attached by means of adhesive. To this end, the dampingelement 20 is glued both into therecess 21 of the base plate and into therecess 22 of the support plate. Also in this case, a small gap remains between the twoplates plate 20 shows the advantage that no further connection exists between the twoplates - Even if both the
chuck 1 and thepallet 2 are provided with a dampingelement chuck 1 with a dampingelement 20, or to provide only thepallet 2 with a dampingelement 7. Moreover, the damping characteristics of the dampingelements elements
